The 7-55 will not only be available in white, but will also be available as a memeber of the golden series from B&O 😁 But none of them are available for ordering until early next year.
The white 7-55 is even posted on B&O's media centre now. Our understanding is that the BL 7-2 and 7-6 will be available in white first, followed by the 7-4 shortly after (the 7-4 is shown in the first post in this thread).
